Space Frame Cane

May 11, 2013

A test cell was cut on the water jet to validate the tool offsets that had been empirically resolved as well as to validate methods for cuts made with intersecting profile projections.

First, a 2X2 work piece was profiled.

After the detailed block was created it was cut in the opposite direction.  But first, in order to prevent stream scattering, wax of an hard durometer was molten and poured into the voids left from the original cut.

The the wax-logged part was cut in a perpendicular direction:

A third direction was cut, without logging it with wax.  That did not come out as cleanly, or completely, as the second did.  Without as much material to remove, it should have cut more cleanly.  But that intuition proved false in this trial.  There is apt to be coherence lost in the jet that made the outer side of the cut so jagged and impartially penetrated.

After the final cut, we played with how strong the little armature was.  You can see it’s quite strong.  Brian weighs 165 pounds.  I, unfortunately, weigh closer to 350 pounds!

Progress on the Space Frame Cane:  A trial cut of the handle was made and it became clear there would be some complications in water jet cutting at that depth.  And, issues with cutting in an additional, orthogonal direction.  These were addressed with a test piece.
